Time shift after resume

Question asked by mathew_k_t on Oct 10, 2018

Hi,

 

I'm using iMX6ULL Board. I have two instances of the same device, both are connected as IIO devices.

 

These two devices produce ADC ready interrupts. Normally, it follows a difference of 5ms between the devices.

 

But, each time when the devices wake up from suspend mode 5ms is increased by 100usec.

 

What's the reason for this timeshift?

How to avoid it or maintain 5ms difference?
